Stop chasing a mouse around. Your trackball stays in one place and puts control under your thumb, so you don't have to move your arm to move your cursor. And its sculpted shape supports your hand for comfortable control all day long. This trackball includes the Logitech® Unifying receiver. The tiny wireless receiver stays in your laptop, so there's no need to unplug it when you move around. Plus, you can easily add a compatible keyboard, number pad or mouse-without the hassle of multiple USB receivers. You can go for up to 18 months without changing batteries-and, the convenient battery indicator helps to ensure that you'll never be caught off guard. Battery life may vary based on user and computing conditions. You get precise cursor control wherever you want to use your trackball. Hard tables, comfy sofas and lumpy beds are all no problem for the M570. The integrated scroll wheel and easy-to-reach Back/Forward buttons make control simple, whether you're Web surfing on a laptop or navigating a home-theater PC.
